这个 yaml 有什么问题

Whats wrong with this yaml

它说 YAML 在此特定行无效 Access-Control-Allow-Origin: * 我错过了什么

http:
  - request:
      path: /
      method: GET
    response: 
      headers:
        Server: Apache
        Last-Modified: Mon, 29 Mar 2021 15:54:09 GMT
        Etag: "19bbb-5beaee46ce7fa"
        Accept-Ranges: bytes
        Content-Length: 105403
        Vary: Accept-Encoding
        Set-Cookie: HttpOnly;Secure;
        Access-Control-Allow-Origin: *
        Content-Type: text/html
      file: 0.html
      status: 200

* 是一个特殊字符。 做到 "*"
